l sILO. l

Tou/.ZZ who/m, t may concern! Be it known that I, BENJAMIN 'SHILL-` iNG,a citizen ofthe United States, and a resident of Knox, in the county ofStarke and State ofIndiana,have"inventedT a certain new and usefulImprovement vin Silos, of which the following is a specification.

My present invention relates generally to silos, `and more particularlyto a metal silo construction, my object being to provide a silo, moreespecially aconstruction adapted to the `formation of silo tanks for thestorage of grain, and like'structures, of a take-down portablenatureadapted to the needs of renters and others to whom thev transportationof a construction of this nature, fromplace to place, is a considerationof great moment.

It is the obj ect of myinvention, therefore, to provide a' jointedconstruction of the type above set forth, having means whereby thejoints may be rendered waterand air-tight, and their connection anddisconnection read# ily and quickly eected. j j

A still further' object of my invention is tofprovide a jacketsurrounding thetank and providing for the reception of a layer ofinsulating material ofsuitable nature, to prevent the contents of thetank from freezing, together with certain novel means whereby tosupportfthe acket in position, as hereinafter described.Y

lVith these and certainother objects residing for the most part in thedetails of construction, all of which will be better understood from thefollowing description, refer ring to the accompanyingdrawing forming apart of this specilication and in which!- Figure 1 is a side elevation,the upper portion of the acket removed;

Fig. 2 is a bottom plan view of the base;

Fig. 3 is a horizontal section through a portion of the silo wall takensubstantially on line 3-3 of Fig. 1;

Fig. t is a vertical section taken substantially on line 4 4 of Fig. 3,and

Fig. 5 is a horizontal section taken adjacent the door.

Referring now to these figures, my improved take-down constructionincludes a base 10, an upright cylindrical tank in upper and lower parts11 and 12, the lower end of which tank rests upon the base 10, and ajacket 13 surrounding the tanks in spaced relation to the major portionof the tank surface, to provide for the introduction of a layer of haystraw, or other material, as at Specification of Letters Patent.

IApplication filed November 7, 1916. Serial No. 130031.`

14 in Fig. 3, calculated to insulate the tanks and prevent the contentsthereof from freez- 1ng. v

i/Vhen used as a silo, my improved' construction is, of course, providedwith a top or cover 15, which may be of the usual coni cal type, asshown in Fig. 1.

The base 10, as clearly seen in Fig. 2, is formed of a plurality ofsegmental sections 16, and is in the formof a ring, with its sections 16connected in detachable relation at their 'adjoining ends by means ofbolted ish plates 17 and the like, upon the lower surface of the ring.This ring may, of course, be lilled in with straw, hay, or a suitable ordesired composition.

The tank sections 11 and 12, as particu` larly seen in Fig` 1, overlapone another at an intermediate point, the lower portion of the upperpart 11 depending below the upper portion of the lower part 12, eachpart being composed of a plurality of segmental sections havingoutstanding flanges along their vertical edges, disposed` in spacedrelation as indicated at 18, and seen particularly in Fig. 3, withinterposed sealing strips 19, preferably formed of wood with surfacepitch, paint, or other material calculated to form an airand water-tightoint when the flanges 18; are bolted by the vertically spaced connectingbolts 20 which extend also through the sealing strips 19. i

j It will be noted from Fig. 1 that the lower port-ions of the vflanges18 of the upper tank part 11 are slightly offset in order to `em bracethe upper portions of the flanges 18 of j the lower part, 4theoverlapping lower portion of the upper part being preferably cemented byan elastic cement and the like to the upper portion of the lower part 12in order to exclude air and water without materially increasing thelabor of detaching the several sections.

Where the construction as thus described is used as a silo, with the topor cover 15 as before described, the sections of the upper and lowerparts 11 and 12 are at certain points provided with widely spacedflanges 21, as seen in Fig. 5, and connected in such spaced relation bymeans of rods 22, for the support of door sections 23, the latter ofwhich are as usual pressed outwardly by the material within the tank, toclosed position.

The jacket 13 is in a plurality of sections of segmental form, the' endsof which overlap one another circumferentially of the tank and bearagainstv the connected flanges' 1S and 21 thereof, as seen particularlyin Figs. 8 and 4, such overlapping ends of the jacket sections beingprovided with apertures 24, as in Fig. 3, through which eye? bolts 25extend, in a vertical series adjacentV the connected flanges 18 of thetank, so that v ready disconnection and removal.

In practice Vthe tank proper, `including the upper and lower parts 11and 12, and the several sections thereof, are formed of comparativelyheavy metal of anature unsusceptible to the attacks 0f ensilage acids,although the jacket 13 may be formed of material considerably lighter inweight than the tank itself, in view of the fact that it is removed fromthe influence of the ensilage at all times.

It is further obvious that a silo, constructed in accordance with myinvention, does entirely away with the usual cumbersome hoops and otherattachments supporting the same, and extremely diiiicult of adjustmentto proper position, and that the several sections may be readily andquickly erected and detached, without in any manner impairing the sameor lessening their capacity of future use.

It is further obvious that my invention provides a simple, comparativelyinexpensive construction, which may be erected and taken down withoutthe use of skilled labor, which will hold and protect its: contents fromexterior influences, and which will permit of ready transportation whenits sections are detached and removed.

I claim 1. A construction of the character described, including avertically disposed Copies of this patent may be obtained for ve centseach, `by. addressing th cylindrical tank in vertically lappingportions, each portion including a plurality of similar sections `havingparallel opposing and upstanding vertical lianges,bolts extendingthrough and connecting the said flanges, and an outer shell 1n annularlyspaced relation to the outer faces o f the tank sections, said shellincluding similar annularly lapped portions, the lapped portionsV ofwhich abut the outer edges of the said connected iianges of the tanksections, and are provided with alined openings, and connecting membersextending through the said openings to join the said sectionsof theshell, said connectingv members engaging portions of the tank whereby tohold the shell against displacement with respect thereto.

2. A construction of the character described, including a. verticallydisposed` cylindrical tank lin verticallylappingportions, each portionincluding a plurality of similar sections having parallel Y opposing andupstanding vertical flanges, bolts extending through and connectingthesaid flanges, and an outer shell in annularly spaced relation to theouter faces ofthe tank sections, said shell including similar annularlylapped portions, the lapped portions of which abut the outer edges ofthe said con# nected flanges of the tank sections and are provided withalined openings, eye-bolts engaging portion of the connecting bolts ofsaid tank flanges and extending outwardly through the alined openings ofthe inner sections whereby to connect the latter to one another, andanchor the shell to the tank to prevent displacement thereof.
